I've been wanting to try to learn how to make music with FT for quite a while, so I thought I'd try my hand by making some covers. This is the first of those. I was overall pretty happy with how it turned out!

The only issue is that some stuff sounds dissonant when I feel like it shouldn't. In 0A particularly, the octave A's sound pretty harsh. Why is this, and how can I fix it?

Also the only way I think I could put those triplets in was to make a ton of instruments, which I did. Is there an easier way, or was that the right call?

Great job on this! If I didn't know better, I'd think I was hearing the real NES audio. I don't hear any dissonance, everything sounds pretty much identical to the real game music. For triplets, I usually just track the notes and use the Gxx effect to time the triplets. But, your way works just as well.
